feat(core): Add commands to workers to respond with current state (#7029)

This PR adds new endpoints to the REST API:
`/orchestration/worker/status` and `/orchestration/worker/id`

Currently these just trigger the return of status / ids from the workers
via the redis back channel, this still needs to be handled and passed
through to the frontend.

It also adds the eventbus to each worker, and triggers a reload of those
eventbus instances when the configuration changes on the main instances.
